针对现有的测量雨区衰减方法受到标定局限性的限制,导致测量值存在偏差的问题,提出基于标定源的双偏振天气雷达雨区衰减测量偏差修正方法;安装双偏振天气雷达设备,并测量雨区衰减数据,以测量衰减数据为偏差修正的初始数据,分析测量偏差来源与类型;利用标定源对双偏振天气雷达设备进行标定,实现雨区衰减测量偏差修正。修正效果测试对比实验结果表明,与传统的偏差修正方法相比,该修正方法在大部分区间内的回波统计值更大,修正效果更加明显。

基于Fluent软件建立三维模型,采用SST k-ω湍流模型,对含沙量在0.05、0.5和5 kg/m3,柱体表面粗糙度在0、0.1%D、0.3%D、0.5%D、0.8%D和1%D时单圆柱绕流的柱体的受力特性及冲蚀进行数值模拟,研究了不同含沙量水流作用下,粗糙度对圆柱的平均阻力系数、升力系数及冲蚀率的影响。结果表明:在同一含沙量的水流作用下,柱体的升力系数在粗糙度为0.5%D时达到最大值;当柱体表面粗糙度相同时,平均阻力系数受水沙流含沙量的影响较小,升力系数受含沙量的影响较大;在不同

为了降低制造车间传感网能耗,采用基于菌群优化的径向基函数神经网络算法对传感网数据进行融合,去除冗余感知数据并降低数据维度;首先分析传感网节点的分簇及数据传输方式,然后建立基于径向基函数神经网络的生产车间传感网数据融合模型,引入菌群算法,利用菌群算法的趋化、复制和迁徙操作对神经网络的权重进行优化,获得稳定的径向基函数神经网络结构。结果表明,相比常用传感网能耗优化算法,采用菌群优化的径向基函数神经网络优化效率高,在网络能量一定的情况下,能有效减缓节点的“脱网”速度,并增加汇聚节点的接收数据量,通过改变菌群趋化
